Abstract: 348,557. Totalizators; counting-apparatus. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Stewart, C. E. ; 4033, Marshall Road, Drexel Hill, and Johnstone, A. J. ; 45, Primos Avenue, Folcroft, both in Pennsylvania, U.S.A.) Dec. 10, 1929, No. 37857. Convention date, Jan. 26. [Class 106 (i).] In an electric totalizator or like system the impulses, which may be of different values, are collected by automatically started and rotated selector switches and are received by other switches .and transferred by these as impulses of one value to the first of a series of counting switches. The invention may be applied to the sales of tickets generally and to the totalizing of the readings of integrating power meters. General arrangement. The initiating act, for example, the sale of a ticket of a certain value, momentarily separates contacts at 1 or 2, Fig. 1, while similar operations in the case of other values breaks circuit at 3 or 4, and at 5 or 6. The impulse caused by breakage of circuit sets a collecting switch A or B rotating and an impulse is thus permitted to flow during the rotation to step forward a switch A<1> or B<1>. After a certain number of advances of this switch, according to the value of the initiating impulses in the group, an impulse passes to a switch C and this in turn controls the sending of impulses to a counting switch C<1> and thence in cascade to other denominational switches D, E. Grand totals may be obtained by means of a further installation shown in Fig. 2 which receives and totalizes impulses arriving from a number of systems such as that of Fig. 1. Collection and transmission of impulses. A relay 1<1> normally energized is de-energized by the momentary displacement of contact 1 and this through contact 1<a> completes circuit for the magnet 19 to advance the switch A one step. The relay 1<1> is then re-energized through wiper A-1 thus allowing further advance of the switch which consequently continues in rotation until it reaches home position. When the wiper A-2 reached its first off-normal contact it transmitted an impulse to the stepping-magnet 7 to advance switch A<1> one-step. If contact 2 has also been operated the wiper A-2 will send a further impulse when it reaches its second contact and similar results obtain if other contacts in the group are also operated, irrespective of the order in which this takes place. Counting and transfer of impulses to switch C. When switch A<1> leaves its normal position a relay 8 is de-energized by the wiper A<1>-1 but the operation of its armature, included in a feed line to a relay 9 is ineffective as this relay is also supplied by connection with the first off-normal contact of the bank A<1>-3. When, however, the wiper A<1>-1 reaches its fifth contact relay 8 is re-energized, and relay 9 is operated to send an impulse through line 21 to wiper C-3 to set switch C in rotation. When wiper C-2 engages a contact wired at 23 to contact 9a of relay 9 an impulse is transmitted through line 12 to magnet 13 to advance switch C<1> through one step. In the example given each originating impulse of the first group has a value of 2 and through the action of switch A<1> therefore the advance of switch C<1> represents a value of 10. Similarly contacts 3 and 4 each have a value of 5 and the corresponding switch B<1> is wired so as to enable the wiper B<1>-1 to effect transfer at every other step to produce an impulse through wiper C-2 also of value 10. Contact 5 has the value 10 but contact 6 is given the value of 50 and consequently controls five relays 6<1>, 6<11> ... With any of the relays 5<1>, 6<1>, 6<11> .. operated therefore the collecting switch is enabled to transmit an impulse of 10 or five impulses each of value 10. Counting switches C<1>, D, E. Each impulse denoting 10 transmitted by switch C through line 12 operates the stepping magnet 13 of switch C<1> and when ten such impulses have been received the wipers C<1>-1, C<1>-2 in conjunction with the wiper C<1>-3 effect the de-energization of relay 15 so that an impulse is sent through wiper D-5 to the magnet 16 which thereupon advances the hundreds switch D. As in the case of switch A<1> the movement of switch D is at once followed by four more steps to bring the wipers to the fifth (tenth, fifteenth, &c.) contact and thus enable one revolution of the switch to represent ten impulses received. Transfer to switch E similarly occurs when wiper D-1 completes a revolution, circuit to magnet 17 then being made and the switch E advancing five steps to its next indicating position. Indicating grand totals. The equipment shown in Fig. 2 totalizes the impulses of all such systems as that of Fig. 1, the switch F serving to collect the impulses arriving through lines 35 and operating the relays 33, 34 &c. The collected impulses pass through line 31, contact 31<1> of relay 56, Fig. 1, line 32 and magnet 36 to advance the first counting switch F<1>, representing hundreds. Transfer to the thousands switch G takes place as in Fig. 1. Zeroizing the switches A<1>, B<1>, C<1>, D, &c. This is effected by setting a contact 30, Fig. 1, to cut out relay 56 and energize relay 29. The contacts of relay 56 are included in the various impulse and transfer circuits so that these are now broken and the contacts of relay 29 close homing circuits for all the counting switches. Displaying totals. As shown in Fig. 1 the totals may be displayed by pointers moving over dials or numeral lamp circuits may be closed by contacts of one wiper, of each counting switch. If desired the switches A<1>, B<1>, C<1> may also control lamp circuits to indicate respectively the values standing on these switches. In a further arrangement, Fig. 5, a monogrammic sign is utilized the lamps being connected up with the contacts of relays 44 .. 51 and the bank contacts I-1, I-2 of the counting-switch. The relays are controlled by the banks I-3, I-4. Specification 325,073, [Class 106 (i), Calculating &c.], is referred to.
